Apparently there was a problem because I am supposed to self-medicate using this specific asthma medication because the test can sometimes cause asthma attacks. I told them my asthma is very mild and I haven't had an attack in ages (they actually asked me when my last attack was and what it felt like). But that wasn't good enough. So they turned me away and I have to reschedule after getting this medication from one of my other doctors.
So my mom took off a day of work, I took off a day of work, got up very early, drank that liquid, went without breakfast or my medication... for basically nothing. And if someone had told me in the first place that I needed to take this medication beforehand, it wouldn't be so. *sigh*
Test was rescheduled for next Monday morning. I'm hoping they get it right this time. On the up side, my arm is feeling pretty good today (*crossing fingers that orthopedic physician's assistant doesn't ruin that tomorrow*).
